PZ-33 Polyfunctional Aziridine

Pentaerythritol Tris (3-(1-Aziridinyl) Propionate

PZ-33 is an ethylene imine based tri-functional polyaziridine with a functionality of 3.3. It provides the highest level of cross-link density, which yields the greatest improvement in physical and chemical resistant properties. And, not have a methyl group attached to the aziridine ring it is the fastest reacting polyfunctional aziridine cross-linker.

PZ-33 is used to cross-link aqueous and non-aqueous coatings, inks, overprint varnishes, and adhesives.

This polyfunctional aziridine functions as the aziridine end groups react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. For more information, see: Reaction Mechanism.
